Lucy weighs 6.6 pounds and gains 1.7 pounds per year. Biggie weighs 12.9 pounds and gains 1 pound per year. How many years will it take until the two cats weigh the same amount?

9  years

Step-by-step explanation:

Lucy weighs 6.6 pounds and gains 1.7 pounds per year

The expression above can be expressed mathematically as;

1.7x + 6.6

where x = number of years

Biggie weighs 12.9 pounds and gains 1 pound per year.

The expression above can be expressed mathematically as;

x + 12.9

where x = number of years

How many years will it take until the two cats weigh the same amount?

1.7x + 6.6 = x + 12.9 (Solve for x)

1.7x - x = 12.9 - 6.6

0.7x = 6.3

x = 6.3 / 0.7 = 9 years
